We propose a relativistic quantum Otto cycle between an entangled state of two qubits and their composite excited (or ground) whose efficiency can be greater than the usual single qubit engine. The hot cold reservoirs are constructed by providing uniform accelerations to these along with interaction background field individual qubits. efficiency, as measured from one qubits' frame, not only dep...

In colorings of some block designs, the vertices blocks can be thought as hyperedges a hypergraph H that placed on circle and colored according to rules are related circular mixed hypergraphs. A is called if there exists host cycle vertex set X such every edge (C- or D-) induces connected subgraph this cycle. We propose an algorithm color (r,r)-uniform, complete, circular, hypergraphs for all f...

The NA60 experiment at the CERN Super Proton Synchrotron has studied dimuon production in 158A GeV In-In collisions. The strong excess of pairs above the known sources found in the complete mass region 0.2<M<2.6 GeV has previously been interpreted as thermal radiation. We now present first results on the associated angular distributions. Using the Collins-Soper reference frame, the structure fu...
